Nexus AI is a cyberpunk-themed terminal interface for chatting with LLMs, generating images, playing browser games, and tracking high scores. Built solo by Xavier Scott (THYFWX). It runs at thyfwxit.com/nexus.
Most AI chat interfaces feel like search bars with extra steps. Nexus is the opposite. It's a full retro-futuristic terminal you can boot into, talk to, and waste time inside. Tools, games, and AI are wired together into one place because that's how I wanted to use them.
Xavier Scott. Systems specialist, hardware repair tech, and homelab tinkerer. I wire networks, fix logic-board damage on Apple devices, run Proxmox at home, and build custom PCs as a hobby. Nexus is what I shipped when I wanted a portfolio that wasn't just a PDF.
I build with code, I just don't write it by hand. There's no team behind this. It's me, my toolchain, and a small AI budget I cap each month.
4 AI CHAT MODESNEXUS: general conversation, questions, creative writing. CODER: programming help, debugging, system design. EDUCATION: structured learning, study help, explanations.
